Effects of Locomotion Training With Assistance of a Robot-Driven Gait Orthosis in Hemiparetic Patients After Subacute Stroke

February 17, 2014 updated by: Yonsei University

The investigators aimed in this study to investigate the effects of 4 weeks robot-assisted locomotor training on motor recovery of lower extremities and walking ability compared with the conventional gait training in subacute post-stroke non-ambulatory hemiplegic patients.

72 first-ever stroke patients who could not walk independently (FAC < 2), and suffered within 6 months were enrolled and randomly assigned into 2 groups. The subjects with congestive heart failure, malignancies, cardiopulmonary dysfunctions, and who could not walk independently before stroke attack were excluded.

Two groups received 30 minutes conventional gait training including Neurodevelopmental Treatment (NDT) basically. The robotic assisted locomotor training group received additional robotic-assisted gait therapy for 30minutes with Lokomat® (Hocoma, Zurich, Switzerland) daily for 4 weeks, and the conventional gait training group received additional daily conventional gait training with NDT for the same periods. The independent walking ability(FAC ≥ 3), Functional Ambulation Category (FAC), Motricity index (MI), Fugl-Meyer assessment (FMA), Modified Barthel Index (MBI), Medical Research Council (MRC) for each lower extremity muscles were assessed before, during (2weeks) and after training. And the independent walking ability were followed until 3 months.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 80 years (Adult, Older Adult)

Accepts Healthy Volunteers

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
change of functional ambulation category point
Time Frame: baseline, during training (2weeks), post training (4weeks) & followed for 2months after training
FAC is a functional walking test that evaluates ambulation ability. This is an 6-point scale.
baseline, during training (2weeks), post training (4weeks) & followed for 2months after training

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures.
